Quantum Informational Gravity (QIG) is proposed as an effective scalar-perturbation cosmological framework compatible with General Relativity and Einstein–Boltzmann evolution. The framework introduces a localized perturbative sector capable of generating coherent projected structure signatures in tomographic weak-lensing observables. A sequence of phenomenological tests performed on DES-style tomographic projections demonstrates: - coherent feature recovery, - stable localization of the preferred perturbation scale, - projection consistency across tomographic bins, - survival under mild marginalization, - and compatibility with lightweight CLASS-style evolution tests. Importantly, QIG does not behave merely as a tuned best-fit template. The observed behavior repeatedly favors coherent recovery and structured localization rather than random fit absorption or unconstrained parameter drift. The current implementation focuses on phenomenological cosmological structure analysis and tomographic projection behavior rather than complete cosmological replacement modeling. The remaining stages of validation focus primarily on: - covariance-complete sampling, - cross-survey robustness, - Planck/CMB integration, - and precision Bayesian inference, rather than initial phenomenological viability.
